Phys.org / Chimpanzees have accents too, study finds
A study has found that young chimpanzees develop distinct population-specific vocal patterns as they mature (ontogeny), challenging the long-held assumption that their calls are inflexible and determined solely by genetics. ...
Medical Xpress / Stopping chronic pain before it starts: Surprising biological pathway may play key role
Chronic pain is one of medicine's most stubborn puzzles. A sprained back, a surgical incision or a pinched nerve heals—and yet, for millions of people, the pain never fully goes away. Why some injuries fade into memory while ...
Phys.org / Wrinkled or smooth? Cell growth mechanics determine shape of plant organs
When inner and outer cell layers of sepals—the leaf-like plant organs that cover and protect the flower bud before it opens—all grow upward, the organs stay smooth and uniformly stiff, which is optimal for the plant, according ...
Phys.org / Trapped light generates nanoscale magnetization
Using an engineered metasurface that traps light, Cornell researchers have demonstrated a new way to generate strong static magnetic fields without using external magnets or magnetic materials—an approach that could advance ...
Medical Xpress / Cerebral palsy might be a collection of symptoms, not its own disease
Historically, cerebral palsy (CP) was linked largely to events at birth, including prematurity or temporary loss of oxygen to the brain, but research over the past decade has suggested that genetic factors contribute to CP ...
Phys.org / Microbial 'dark matter' yields 173 potential carbon dioxide-fixing strains
There are millions of species of bacteria and archaea on Earth, remarkably little is known about most of them. Now, researchers have mined the genomes of thousands of microorganisms preserved at the RIKEN BioResource Research ...
Tech Xplore / Metal foam front rails could make cars safer in collisions
A new study finds that composite metal foam (CMF) could significantly improve automobile safety during frontal collisions. Using computational models to run detailed simulations, researchers found that incorporating CMF into ...
Medical Xpress / Microdroplets may reduce colorectal tumor growth at potentially lower cost
Scientists from Nanyang Technological University, Singapore (NTU Singapore) have developed microscopic peptide droplets that deliver large amounts of gene-silencing molecules into cancer and immune cells, reducing the growth ...
Phys.org / Bacterial nanoplatform reprograms spleen immune cells to help prevent cancer recurrence
A research team led by Professor Yong Taik Lim at the SKKU Advanced Institute of Nanotechnology (SAINT), Sungkyunkwan University, have developed an engineered nanoplatform named t-SMC (trained immunity-mediated splenic myelopoiesis ...
Phys.org / Pigment found in beets linked to plants' adaptation to harsh environments
The pigments that give beets their red color may have helped a major group of flowering plants repeatedly adapt to dry environments, setting the stage for the evolution of traits that allowed plants to adapt to some of the ...
Phys.org / Surf's up: How the seafloor shapes breaking waves
A new study led by surfing scientists at the Scripps Institution of Oceanography at UC San Diego revealed the physical relationships underlying a pattern familiar to generations of surfers.
Medical Xpress / Healthier fats linked to longer survival after prostate cancer diagnosis
Men diagnosed with nonmetastatic prostate cancer can generally expect to live for many years after their diagnosis. However, cardiovascular disease and other cancers remain important threats to their long-term health. For ...
